Boiler Overheating: Signs, Causes and Solutions

Causes: Most commonly associated with excessive deposition on ID tube surfaces, coupled with a boiler water low pH excursion. Water chemistry upset, such as what can occur from condenser leaks, particularly with salt water cooling medium. Leads to acidic (low pH) contaminants that can be concentrated in the deposit.
